Analysis of a radial flux hysteresis IPM motor

Design of self-start permanent magnet motors over wide operating range has been a challenging topic of interest among the researchers over the last two decades. This paper presents the design and finite element analysis of a novel 1HP 208V 3-phase 4-pole line start radial flux hysteresis interior permanent magnet (IPM) motor. The proposed motor is a solid-rotor self-starting hybrid synchronous motor combining both hysteresis phenomena and permanent magnet excitation inside the rotor. The transient performance analysis results of the hysteresis IPM motor are presented and explained in this paper. Simulation results exhibit that the proposed hysteresis IPM motor has smooth starting and good synchronization capabilities.
